Prime Difference

Given an integer *n*, output the smallest prime such that the difference between it and the next prime is at least *n*.
For example, if `n=5`, you would output `23`, since the next prime is `29`, and `29-23>=5`.
# More Input/Output Examples
1 -> 2 (3 - 2 >= 1)
2 -> 3 (5 - 3 >= 2)
3 -> 7 (11 - 7 >= 3)
4 -> 7
5 -> 23
6 -> 23
7 -> 89
8 -> 89
~~This is code-golf, so shortest code wins.~~
